The first day of spring doesn't arrive until Tuesday, but Mother Nature has fast-forwarded past spring and gone straight to summer over the Midwest. Yesterday, large portions of Michigan, Illinois, Wisconsin, Minnesota, and Indiana recorded their all-time warmest temperatures for so early in the year, including the cities of Chicago, Minneapolis, Indianapolis, Milwaukee, and Lansing. Temperature records for these cities go back as far as 1863. Perhaps the most extraordinary record was set in Traverse City, Michigan, which hit 81°F--a temperature 42°F above the average high for the date, and four degrees warmer than any previous day so early in the year. Records go back to 1897 in the city.

Data for the previous records was taken from NOAA's National Climatic Data Center (NCDC).

Why the record early-season warmth?
The unusual warmth is due to a loop in the jet stream that has created a large upper-level ridge of high pressure that is stuck in place over the Eastern U.S.--a phenomenon known as a "blocking pattern." Since the jet stream acts as the boundary between cold air to the north and warm air to the south, and the large loop in the jet places its axis far to the north of the eastern U.S., summer-like warmth has developed over the eastern half of the U.S. Conversely, colder than average temperatures have developed over the western third of the U.S. behind the southwards-dipping loop of the jet stream. There are at least three large-scale patterns working together right now to create an unusually strong high-pressure ridge over the eastern half of the U.S.:

1) La Niña. The on-going La Niña event in the Eastern Pacific has weakened considerably over the past month, but ocean temperatures there are still cool enough to affect the jet stream pattern, favoring high pressure and warm temperatures over the Eastern U.S., and low pressure and cold temperatures over the Western U.S.

2) The Madden-Julian Oscillation( MJO). The MJO is a 2-month cycle of thunderstorm activity that travels west to east along the Equator. The MJO is currently in phase with La Niña, and is helping create warmer temperatures over the Eastern U.S.

3) The North Atlantic Oscillation (NAO.) The NAO is in its positive phase, which means the difference in pressure between the Icelandic Low and the Azores High is stronger than usual. This tends to increase the jet stream winds and keeps the jet from sagging southwards over the Eastern U.S.

While the blocking pattern responsible for the heat wave is natural, it is improbable that the intensity of the heat would have been so great unless we were in a warming climate. Climate scientist Dr. James Hansen has posted an interesting (as yet unpublished) paper discussing how the odds of such extreme heat events have shifted in recent years. I plan to discuss these concepts in more detail next week.


Figure 2. Predicted high temperatures for Thursday, March 15, 2012 over much of the Midwest are more typical of June than March.

The forecast
The summer-like heat continues today over the Midwest, with the greatest departures from average (30°+) expected over Wisconsin, Iowa, Illinois, Indiana, and Michigan. This area of 30°+ above average temperatures will expand to stretch from South Dakota to New York on Sunday and Monday, then gradually shift eastwards, extending from Wisconsin to Maine by Wednesday. The jet stream loop is predicted to grow more pronounced this weekend, and reach a truly extreme configuration on Monday and Tuesday. On those days, the predicted strength of the upper-level ridge of ridge pressure along the northern tier of states, from Wisconsin to Maine, will be typical of what we see at the height of summer, during July and August. The GFS and ECMWF models are predicting the height at where a pressure of 500 mb is found will range between 5760 - 5800 meters on those days--7% higher than the typical mid-March 500 mb heights of 5460 meters. Record-breaking summer-like temperatures will last until at least Friday, March 23, for much of the Midwest and Northeast U.S.

Extreme jet stream patterns like this often lead to tornado outbreaks in the Midwest, at the boundary of where warm, moist air flowing north from the Gulf of Mexico collides with cold, dry air flowing south. Cold dry air aloft, combined with warm, moist air at the surface, makes the atmosphere unstable, since air rising in thunderstorm updrafts will be less dense than the surroundings, allowing the air to accelerate upwards and increase the intensity of the thunderstorm. This will be the case on Sunday, when NOAA's Storm Prediction Center has highlighted a potential risk area for severe weather from Texas northwards through Nebraska. Fortunately, the winds of the jet stream are expected to blow almost due south to north over the region by Monday, which may limit the amount of cold air aloft that can overrun the warm air at the surface, resulting in a more stable atmosphere and a reduced chance of severe weather compared to Sunday.

I typed up my pre-season hurricane season forecast earlier today. Only took me five hours between talking to friends, tracking tornadoes, talking on here, and doing other things, lol. I'm not going to bore you guys, so here are some of the highlights:

-- Positive NAO, meaning a stronger subtropical ridge.
-- SAL Outbreaks and unfavorable East Atlantic for tropical cyclone development.
-- More close to home formations and landfalls
-- Near normal Sea Surface Temperatures (above in Gulf, below in East Atlantic)
-- Neutral/El Nino ENSO

Numbers: 12-7-4

GEOMAGNETIC STORM ALERT:

A minor Geomagnetic Storm (KP=5) is currently in progress due to an incoming CME shock.
pdated 3/15/2012 @ 21:30 UTC
Moderate Geomagnetic Storm
The ACE Spacecraft detected a sharp increase in solar wind speed to near 800 km/s. This indicated the arrival of an incoming CME shock past the spacecraft. A geomagnetic sudden impulse measuring 27nT was just detected shortly afterwards by the Boulder, Colorado Magnetometer at 13:09 UTC and this signaled that the interplanetary shock had swept past our planet. A moderate G2 Geomagnetic Storm resulted, but is slowly declining. The Bz component of the Interplanetary Magnetic Field was pointing sharply south for long durations.

Be on the lookout for Aurora at high latitudes.

Quoting Neapolitan:
The preliminary numbers say 411 high temperature records were set or tied today across the United States, along with 298 high minimum records, for a total of 709. By the time final numbers are tallied, the total should come in around 900 or so, meaning today set or tied more high temperature records than any day this year or last (April 10, 2011, saw 785 high records).

For the month to-date, 1,590 new daily record highs have been set vs. 94 new daily record lows, for a ratio of 16.91 to 1. And the current heat wave is expected to last through at least the middle of next week.

This is pretty scary, you know.
For a couple of years now, some people (me for one, actually) have been saying that weather forecasting for periods longer than a week is pretty irrelevant considering how fast the Climate is changing.

The fact is, we really don't have any data anymore to base our forecasts on simply because we have never been 'here' before.

An episode like the one which is the topic of this blog is so unusual and unpredicted. And yet after the fact we can make good assessments of why it happened.
But we still can't predict it.

Scary...

Perth Tropical Cyclone Warning Center
Tropical Cyclone Advice #12
SEVERE TROPICAL CYCLONE LUA, CATEGORY THREE (16U)
9:00 AM WST March 16 2012
===========================

At 8:00 AM WST, Severe Tropical Cyclone Lua, Category Three (968 hPa) located at 16.2S 115.9E or 515 km north northwest of Karratha 540 km north northwest of Port Hedland has 10 minute sustained winds of 65 knots with gusts of 90 knots. The cyclone is reported as moving east southeast at 11 knots.

Hurricane Force Winds
===================
25 NM from the center

Storm Force Winds
=================
80 NM from the center in northeast quadrant
50 NM from the center in southeast quadrant
50 NM from the center in southwest quadrant
80 NM from the center in northwest quadrant

Gale Force Winds
=============
180 NM from the center in northeast quadrant
120 NM from the center in southeast quadrant
120 NM from the center in southwest quadrant
180 NM from the center in northwest quadrant

Dvorak Intensity: T4.5/4.5/D0.5/24 HRS

Tropical Cyclone Lua has intensified to a severe tropical cyclone and is now moving towards the east Pilbara coast.

Gales are currently being experienced in offshore Pilbara waters and are expected to develop in coastal areas between Whim Creek and Bidyadanga late Friday night. Very destructive winds with wind gusts in excess of 170 kilometres per hour are likely to develop in coastal areas near the centre of the cyclone during Saturday. Gales are expected to extend to remaining coastal areas between Cape Leveque and Mardie during Saturday and then to inland eastern Pilbara areas later on Saturday.

Heavy rainfall is expected near the west Kimberley coast and in coastal and inland parts of the east Pilbara. During Saturday and Sunday areas of heavy rain are likely in the east Gascoyne and northern Goldfields.

Heavy surf conditions are expected along the east Pilbara and west Kimberley coast during Friday and Saturday.

Tropical Cyclone Watches/Warnings
=================================

A Cyclone WARNING is current for coastal areas from Cape Leveque to Mardie, including Port Hedland, Karratha, Dampier and Broome, as well as adjacent inland parts of the eastern Pilbara.

A Cyclone WATCH is current for the central and eastern inland Pilbara including Telfer, Newman and Paraburdoo, the far western inland Kimberley, the eastern Gascoyne including Meekatharra, and the far western Interior.

Forecast and Intensity
===============

12 HRS: 17.3S 117.7E - 75 knots (CAT 3)
24 HRS: 19.0S 119.4E - 85 knots (CAT 3)
48 HRS: 24.7S 119.8E - 40 knots (CAT 1)
72 HRS: 30.6S 121.2E - 30 knots (Tropical Low)

Additional Information
=======================

Position is based on recent microwave passes.

Dvorak analysis based on embedded center give a DT of 4.5 consistent with MET 4.5 based on a trend of D-. Final intensity estimate is 65 knots 10-min mean while ADT/AMSU intensity estimate is 70 knots.

Shear has begun to decrease [-10 knots at 18Z] and the system is heading into an area of lighter shear during the day. Conditions are favorable for further development during Friday with the system expected to remain a severe tropical cyclone until landfall along the east Pilbara coast during Saturday. Shear increases as upper northwesterlies increase over the system during Saturday but this may not occur in time to weaken the cyclone prior to landfall. The system is likely to maintain TC intensity into Sunday morning as it moves over inland parts of Western Australia.

There is very good general agreement across model guidance for a coastal crossing on Saturday, although the timing of this varies somewhat.

The next tropical cyclone bulletin on Tropical Cyclone Lua from the Perth Tropical Cyclone Warning Center will be issued at 4:30 AM UTC..
